PORTABLE STOVE-HOOD.

SPEGIFICATIONfOrming art a Letters Patent No. 603,730, dated May 10,1898.

To all whom it may concern:

Be it known that I, LOUIS B. KELLER, of the city of Minneapolis, countyof Hennepin, State of Minnesota, have invented certain new and usefulImprovements in Portable Stove-Hoods,of which the following is aspecification. i

My invention relates to portable stovehoods adapted for use upon stovesor ranges and whereby the, steam, fumes, and odors from things cookingupon the stove are drawn off and carried into the chimney instead ofrising into the room and finding their way throughout the house.

The object of the invention is to provide a portable hood adapted toaccommodate a single cooking utensil at a, time and which may be usedupon any stove or range and with a slight modification made applicableto gas or gasolene stoves.

A further object of the invention is to provide a device wherein thecooking utensils may be placed or from which the same may be removedwithout moving said device or hood,and, further, to provide a portablestovehood wherein the draft may be regulated,

and, further, to provide a device to accom plish the above results withthe least possible expense, whereby the hoods are placed with in thereach of every one.

The invention consists in general in. the constructions and combinationsof parts hereinafter described, and particularly pointed out in theclaims.

The invention will be more readily understood by reference to theaccompanying drawings, in which-- Figure 1 is a perspective view showinga stove and a portable hood thereon embodying my invention. Fig.2 is anenlarged sectional View of the portable hood. Fig. 3 is a partialhorizontal section of the same substantially on the line a: w of Fig. 2.

In the drawings, 2 represents a cook-stove, two holes 3 and 4 of whichare practically covered by the portable hood. The lids 5 are removedfrom these holes.

6 represents a low and preferably conical cover for the rear hole 4, andthe same carries and serves as a base for the upright tube 7, which ispreferably of less than one-half the diameter of the stove-hole. Theupper Application filed March 16,1897. stall In. 627,786. on model.)

end of this pipe is closed by a low cap 8 (see dotted lines, Fig. 2) orby a taller condensercap 9, having a greater area upon which the steamis cooled and thus prevented from creating a back pressure in the hood,which would cause the smoke and odors to be forced outward into theroom. In plan section the hood is V-shaped, the sides 10 thereofdiverging from the pipe or flue 7. These sides extend out to about themiddle of the front hole in the stove when the flue 7 is central overthe rear hole. The lower edges rest upon the top of the stove. The topof the hood is formed by the inclined plate or seat 11, which is higherat the back than in front, the same sloping toward the front of thestove. The top 11 is continued in the hinged section 12 and the sides inthe hinged flaps 13. In the forward side of the tube or pipe 7 is a slot14, and 15 represents a semicylindrical slide arranged within the pipeor flue 7 and having a knob 16 extending through the slot 14 and bywhich the slide may be raised and lowered. The slot is preferablyenlarged at the top and bottom of the pipe 7, and the slide 15 is alength less than the pipe 7, so that when adjusted at a middle heightquite a large opening will be left above and beneath thesame leadinginto the pipe 7 and from thence into the stove.

17 represents a handle on the top of the hood, by means of which thehood may be carried from place to place. In one or both sides of thehood I preferably provide a hole 18, closed by a suitable cap or slidewhich maybe removed to admit the spout of a teakettle or of akettle-cover. In this way where suitable covers are provided for thekettles the odors and steam may be drawn off from several kettlesthrough a single hood.

The arrows in Fig. 2 illustrate the currents of air, steam, and smokewhich rise from the kettle that sits on the stove beneath the hood. If ahigh kettle is being used, the steam therefrom would naturally riseclose to the top of the hood and a little of-it would be exhaustedthrough the lower hole 20, beneath the slide 15. Hence in such a casethe slidewould be slipped down to enlarge the hole 21 above it, so thatthe greater volume of steam, 850., would pass into the top of the pipe 7and its condenser and thence be drawn downward into the stove and thenceout through the chimney. On the other hand, if, as shown in Fig. 1, foodis being cooked in a low skillet or frying-pan, the slide will beraised, so that the smoke, 850., would be allowed the shortest pathbetween the frying pan and the stove-hole 4 and the chimney. When thehinged top section 12 and the sides 13 are folded back, the hood willoccupy but little space. The hinged top is convenient also, as itmay bethrown back to permit easy access to the contents of the utensil uponthe stove.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A portable hood, comprising top and side walls, incombination, with the down pipe or flue, open at its lower end andhaving a condenser at its upper end, said down-pipe provided with anopening in its inner side, substantially as described.

2. A portable stove-hood, comprising top and sidewalls, in combination,with the downpipe open at its lower end and having a flange or base tocover a stove-hole, said pipe being formed within the side walls andhaving a slot or opening in its inner side and a slide provided in saidslot, as and for the purpose specified.

3. A portable stove-hood, comprising an inclined top anddiverging sidewalls, said side walls together forming a V, in the opening of which autensil may be placed, a down pipe or flue vertically arranged in theangle between the side walls, said pipe having a slot or opening in itsinner side and provided with a flaring base of a size to cover astove-hole, and said top slanting downwardly from the upper end of saidpipe, substantially as described.

In testimony whereof I have hereunto set my hand this 12th day of March,A. D. 1897. LOUIS B. KELLER.

In presence of- O. G. HAWLEY, RICHARD PAUL.
